Abstract: FIELD: manufacture of building materials. SUBSTANCE: clay mixer with filtering grate has two blade shafts 9 mounted in trough 3, worm blower and filtering grate 5. The new feature lies in the fact that worn blower is set up on one of two blade shafts 9, its worm is assembled of two sections - cylindrical and transition conical ones whose length is not less than diameter of circumferences Д outlined by blades. The diameter ratio in input and output of transition conical section is not less than 1.2. During reprocessing of high-plastic ceramic masses it is advisable to complement the transition conical section with cylindrical worm insert B mounted in trough and having length not less than half Д and to install deflecting blade on neighboring blade shaft in zone of conjugation with B. Innovation concerns equipment for manufacturing building ceramics (bricks, roof tiles), that is devices for preparing ceramic mass to be molded by means of its mixing, reprocessing and, as may be required, cleaning from foreign matters. EFFECT: reduced power capacity both at the expense of replacing two worms by one and due to utilization of worm having small diameter in filtration zone. 4 dwg

Abstract: FIELD: gas purification. SUBSTANCE: invention relates to dry cleaning of gases to remove fine-dispersion dust. Dust catcher has: cylindrical casing having a region with great diameter and smooth transitions to initial diameter; axially arranged entry for swirl gas stream in lower part of casing with enclosed cylindrical displacer and fastened to it fender collar separating casing into separation and dust-catching chambers. Swirl gas stream axial entry disposed in dust-catching chamber has bottom made of sectors mounted for axial rotation. Fender collar is disposed near lower edge in separation chamber. Lower part of the latter is dipped into dust-catching chamber whose diameter is larger than that of lower edge of separation chamber. In upper part of casing, tangential entry for secondary gas stream is available. Axial outlet fitting is changing into a funnel to lower edge of which vertical plates and horizontal sieve are secured. Coaxially with outlet fitting, a tube is installed for vertical displacement with multiple orifices on its side surface close to its lower blind end. To lower part of tube, a grate is fastened, and, between sieve and grate, threads are stretched. Dust catcher with opposite-direction streams contains filter member. In the course of filtration, grate is lifted and pushes the threads to sieve thereby forming thick poil layer which dedusts passing gases. Process of filter member regeneration is effected by way of throwing grate onto threads, shaking it, and blowing through with compressed air. Then grate is held up, fastened, and filtration cycle is continued. Most of dust is separated from dust-gas stream owing to centrifugal and inertia forces. EFFECT: enhanced efficiency of dedusting of gas.
